Application filed November 25, 1912.

To all whom t may concern:

Be it known that I, ROBERT Gr. CLYNE, a subject of the King of GreatBritain, residing at Alton, in the county of Madison and State ofIllinois, have invented certain new and useful Improvements inCartridges, of which the following is a specification.

My invention relates to improvements in cartridges, and moreparticularly to that class or t-ype known as paper shot shells, theprimary object of the invention being to pro-vide a generally improvedcartridge of this class of exceedingly simple construction which will becheap of manufacture, and eflicient in use.

A further object is to provide a generally improved reinforced metallicbase c ap provided at its mouth or rim portion with an inwardlyextending beading forming an interlocking or anchor member andpreventing the tubular paper shell from being forced out of the cap atthe time of tiring, and also forming a battle between the mouth of thecap and the tubular shell portion thereby preventing the escape of gasesbetween these parts, and likewise forming a subjacent annularinterlocking anchor or baflie between the subjacent portions of theshell and the base wad, thereby preventing` the blowing out ordisarrangement of these parts during firing and likewise preventing theescape of gases between the base wad and the tube.

A still further object is to reduce the cost of manufacturing themetallic base cap as compared with the ordinary form of base cap knownas the trimmed or chamfered cap in which the chamfering or trimming isperformed in a machine using a knife to bevel the mouth or upper edge ofthe cap about the inner periphery thereof so that the cap will readilyslip over the tube during the operation of assembling, and whichchamfering or beveling process is notonly eX- pensive but frequentlyresults in imperfect caps due to dull tools and irregular.` alinement inthe holding of the cap during the chamfering or trimming operation.

A still further object is to provide an improved metallic base caphaving a smooth reinforced or non-eXpansible mouth or rim which willprevent the breaking or splitting of the cylindrical side walls of thecap during the operation of assembling when the Specification of LettersPatent.

Serial No. 733,276.

base wad and shell are forced into position or when the cartridge istired.

lVith the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement, and combination of parts,hereinafter described, illustrated in some of its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.

Referring to the drawings, forming a part of this specification, Figurel, is a side elevation of a cartridge constructed in accordance with myinvention, a portion of the cap end being broken away for the purpose ofclearer illustration of the parts. Fig. 2, a perspective view, partly insection, of a slightly modified form of the improved metallic base cap.Fig. 3, a similar view of a further modified form of same. Fig. 4f, aplan view of the form shown in Fig. 3.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The improved cartridge comprisesa paper shell or tube 1, to which issecured the irnproved metallic base cap 2, and an inserted base wad 3,in the improved manner hereinafter referred to. The improved metallicbase cap 2, is provided with the usual peripheral flange 2, for holdingthe cartridge in position within the breech of the gun barrel, while thebase or bottom of the base cap may be provided wit-h a battery cupreceiving opening or primer pocket 2b, as may be desired, for thereception of a battery cup or primer of any suitable and convenientform.

As a means for reinforcing the mouth or rim portion of the base cap 2,as well as providing a combined anchor and baffle member forinterlocking with vthe paper shell or tube l, as well as preventing theescape of gases between adjacent parts'or the disarrangement of suchparts during ring or the eX- plosion of the combustible charge, theupper marginal edges of the base cap are curled or beaded inwardlyforming a reinforcing anchor beading and baflie member 2", which beadingprojects inwardly about the inner periphery'of the cylindrical sidewalls of the cap and forms a'smooth round edge at the mouth of the capfor the purposes above mentioned and hereinafter more fully eX- plained.

After the shell l, and base cap 2, are assembled in proper position, thebase wad 3, it of the type herein shown, may be in-v serted and pressedhome andduring the operationv of pressing the base wad into properposition the reinforcing anchor beading andr baille member 2, at themouth of the cap will be causedv to embed itself into the subjacent orcontiguous portions of the shell or tube thereby forming an annularinterlocking rib or balle portionv la, inthe shell or tube l, andlikewise an annular recess portion 3a, in the subjacent or contiguousportions of the base wad thereby securingly interlocking the partstogether vas against disarrangenient or the escape of the gases orproducts of combustion during the firing of the shell. It will also beobserved that the reinforcing anchorv beading and battle member 2, formsa smooth non-expansible mouth iorthe base cap which prevents thesplitting of the side walls of the latter when the base wad is forcedinto position or during the liring of thecartridge or shell as sometimesoccurs with the ordinary form of cartridge and metallic base cap now inuse. The base wad 3, is preferably, though not necessarily, ein tendedupwardly within the shell l, beyond the plane of the inouth orreinforced portion 2, of the base cap and may bev provided with a largereceptacle vor opening 3b, terminatving ina small centrally locatedopening or passage 3c, leading to the ordinary 'batteryv cup mountedwithin the receiving opening or receptacle 2b, of the base cap.

In Figs. 3, and 4, I have shown a slightly modified forni of reinforcinganchor beading and battle member, in which instance the upper marginaledges of the cylindrical side walls of the base cap are crimped orcrenated into a scalloped beading or vbattle member having the ribbedportions cf, and depressed or indented portions Z) arranged atsubstantially regular intervals, and which scalloped or serrated beadingis adapted to interlock with the subjacent shell for the purpose ofpreventing any circumferential movement between these parts.

From they vforegoing description, taken in connection with theaccompanying drawings, the operation and advantages of my invention willbe readily understood. f

Having thus described some of the embodiments of my invention, what Iclaim and ydesire to secure by Letters Patent is# l. In a paper shellcartridge, a metallic base cap having its edges curled into a scallopedinwardly curled anchor beading.

2. In a paper shell cartridge, a metallic base cap provided with vabattery cup receivingvreceptacle and a peripheral flange and having theupper marginal edges of its vcylindrical side walls curled into anannular anchor beading and baille member.

it cartridge, comprising a tubular inembei' provided with an annularrecess and an interlocking rib or baille portion, a base Wad providedwithv an annular recess portion in interlocking engagement with saidinterlockv ing rib or baille portion, and a metallic base cap providedat its inout-h with an inwardly extending annular beading seated in saidannular recess of said tubular member.

In testimony whereof I have ailiXed my signature in presence of twowitnesses.
